Aspartic Acid in Health and Disease

Area of Science:

• Biochemistry
• Neuroscience
• Metabolic Disorders

Background:

• Aspartic acid (Asp) exists as L-Asp and D-Asp isoforms.
• L-Asp synthesis occurs in mitochondria and muscles; D-Asp arises from L-Asp racemization.
• L-Asp is crucial for protein/nucleotide synthesis, energy metabolism, neurotransmission, and redox balance.

Purpose of the Study:

• To review the diverse metabolic pathways and physiological roles of L-Asp and D-Asp.
• To highlight the involvement of L-Asp metabolism in various diseases and cancer.
• To underscore the need for further research into D-Asp's neurological functions and therapeutic potential.

Main Methods:

• Literature review of aspartic acid metabolism and function.
• Analysis of L-Asp and D-Asp roles in cellular processes and disease pathogenesis.
• Identification of research gaps and future directions.

Main Results:

• L-Asp supports numerous metabolic pathways, including neurotransmission and energy homeostasis.
• Dysregulation of L-Asp metabolism is linked to hereditary disorders, neurological conditions, and cancer.
• D-Asp plays a significant role in brain development and hypothalamic regulation.

Conclusions:

• Aspartic acid isoforms have distinct and critical physiological functions.
• Targeting L-Asp metabolism presents potential anti-cancer strategies.
• Further investigation into D-Asp's therapeutic potential in neurological disorders is warranted.
